Func nav blocker

Template:Brush ent It blocks nav areas touching its AABB to restrict NPCs / Bots from crossing over it.

Note:The entity will NOT start to block automatically: it must first be activated with the BlockNav input.

Bug: For navigation squares touching your func_nav_blocker, if prop_door_rotating, func_physbox, etc. resides on the same squares, UnblockNav along with BlockNav inputs.

Otherwise, the console errors "Area navsquare#[ID] already blocked by a different team id. May produce flow bugs" (Which it does). You can quickly access the faulty nav square by usingnav_mark [ID]followed by nav_warp_to_mark.   [todo tested in ?]

Keyvalues

Team(s) to block (teamToBlock) <choices>

Team this entity should block.

• -1 : Everyone
  Warning: for everyone either edit FGD and use value -2 or turn off smart edit and set that, -1 is not valid and the nav blocker will not work
• 2 : Red , Survivors , Terrorists
• 3 : Blue , Infected , Counter-Terrorists

Note: teamToBlock non-functional, always blocks either for both teams or for no team.

Affects Flow? (affectsFlow) <boolean> (only in )

Does this Nav Blocker block flow in the level? Only Nav Blocker with this enabled will cause flow recomputation on blocking/unblocking.

Important:When this is true don't block the only path to the level's goal with it or the flow won't be computed properly

Inputs

BlockNav

Starts blocking nav areas.
